The term “beast”, used in the book of Revelation from the Christian Bible, is the same beast mentioned in the Faithist Bible. This beast is the “self.” The “mark” is the personality and traits of those who revel in carnal desires and who wish to control others. Thus, when you read “mark of the beast,” it is the same as saying “personality of the beast” or “likeness of the beast.”
Sometimes the evil one, satan, is thought of as the beast because there is no better example of greed, control, confusion, carnality and dread.
